To all whom it may concern,.-` i

Be it known that I, LEOPOLD BAUMEISTER, a citizen of the Grand Duchy ofBaden, residing at Bridgeport, in the county of Fairfieldv and State ofConnecticut, have invented certain new and useful Improvements inMachines for Polishing Wire; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention has for its general object to produce a machine that willperfectly polish all qualities and shapes of wire, from the coarsest tothe finest, either before or after it is tempered.

With these ends in view I have devised the simple and novel constructionof which the following description, in connection with the accompanyingdrawings, lis a specification, numbers being used to denote the severalparts.

Figure 1 isa plan view of the entire machine, the covers of theemery-boxes being removed; Fig. 2, a longitudinal section on the line.fr a: in Fig. 1; Fig. 3, an enlarged cross-section on the line y y inFig. 1, looking toward the left; Fig. 4, an enlarged cross-section onthe lineazin Fig..1; Fig. 5, an enlarged crosssection of one of theboxes; Fig. 6, a detail sectional view illustrating the construction ofone longitudinal section corresponding with Fig. 2, showing the carriagearranged to swing instead of slide.

1 denotes the frame-work, which may be of any preferred construction; 2,tension devices at the front of the machine regulatedby screws 3; 4,winding-drums at the rear of the machine, Land 5 a reciprocatingcarriage at the central portion thereof. Upon each side of the carriageis an cmery-box, 6, through which a strand of wire (denoted by 7)` ispassed to polish it. It will of course be apparent that any number ofthese boxes may be provided in each machine. In the present instance Ihave shown two, that being the number ordinarily used.

The construction and operation of the parts of the machine upon thecarriage constitute an important part of my invention, which I will nowproceed to describe in detail.

Each vbox is provided with upper and lower sets of polishing-rolls,(designated,respectively, as 8 and 9.) The rolls in either or both ofthe sets may be made adjustable. In practice I ordinarily make the lowerset stationary and the upper set adjustable, and have so illustrated theconstruction in the drawings. The

lower rolls are carried by shafts 10, which are journaled in the sidesyof the boxes, stumps 11 being cast upon the sides of the boxes toincrease thebearing-surface and strengthen the machine. The outer endsofthese shafts are squared, and gears 12 are placed upon the squaredportions, as is clearly shown in Fig. 6, this portion of the arrangementof both upper and lower rolls being identical. These rolls may be madeof any suitable material--l for example, wood, leather, lead, o r felt.For ordinary iiat wire I, preferably use a number of thicknesses ofheavy felt, which are slipped over enlargements on shaft 10, and areheld firmly in position bywashers 13 and screws 14, engaging the innerends of the shafts. In

order to preventl emery in the boxes `from working into the bearings ofshafts 10, I pro-` vide collars 15 upon said shafts, which tclosely incorresponding recesses in the sides of the boxes, and leather washers 16between r the feit' and the sides of. the boxes. The screw and washer atthe other end of the roller act to press the felt or other materialfirmly againstv the' leather washer, which, in connection with thecollar, prevents the entrance of any emery whatever into the bearings.Theupper' rollers are constructed in precisely the same manner, but vtheshafts 10 Vare journaled in slides 17, having stumps 18. These slideshave vertical movement in corresponding grooves in the sides of theboxes. (See Fig. ll.)

Any number of rolls may of course be used in each set. shown four rollsin the under set and three in In the present instance I have' the upperset. The stumps and slides yin which porting-pieces 20by screws 21,passing through Y slots 22'* in the sides of the boxes'. Bothsupporting-pieces are provided with lugs 23, and set-screws 24, passingthrough these lugs, en-

gage the top and bottom ofthe side of the motion may be imparted to thecarriage in any suitable manner.

In Figs. 1, 2, and 3 I have shown the carriage provided with rollers 25,which travel upon tracks 26, and are held in position by strips 27, saidtracks and strips being fixed to the frame-work in any suitable manner;and in Fig. 7 I have shown the carriage supported by oscillating levers28. Y

29 denotes the main shaft of the machine, to which power is applied by abelt, (not shown,) and 30 denotes a crank, which may be upon the mainshaft, as in Fig.'7, or upon a secondary shaft, yas in Figs. 1 and 2, inwhich the main shaft is shown as provided with a pinion, 31, and thesecondary shaft with a gearwheel, 32, meshing therewith.

30"l is a link connecting the crank with the oscillating lever.

In Figs. 1, 2, and 3 but a single oscillating lever is used, which ispivoted to the frarnework. At the upper end of this lever is a yoke, 33,and 34 is a sliding block carried by the yoke. A cross-piece, 36, havingarms 35, holds the block in position in the yoke.

37 denotes cross-bolts which extend through both emery-boxes andentirely across the carriage from side to side. One of these boltspasses through sliding block 34, whereby the oscillations of lever 28are caused to impart reciprocatory motion to the carriage.

In order to insure continuous change of the polishingsurface of rolls 8and 9 upon the wire, I cause a partial rotation to be imparted to eachof the polishing-rolls at each reciprocation of the carriage. This mayof course be accomplished in any suitable manner.A In the presentinstance I provide endless chains 38, which engage all of the gears 12upon the shaft of the rolls in each emery-box, passing over and underalternate lower and upper gears. Upon one of the lower shafts in eachemery box I provide a ratchet, 39, -keyed thereto.

40 is a lever which turns on said shaft, and is provided with a pawl,4l, which engages the ratchet. A link, 42, connects each pawl-lever withone of the arms 35, which project from cross-piece 36. It will be seenthat each time the carriage moves toward the right pawls 41 are movedbackward over one or two teeth on ratchets 39, and when the carriage ismoved toward the left this movement must carry the ratchets forward anequal distance, and, through their shafts and the endless chains whichengage all of the gears 12 belonging to each emery-box, impart acorresponding ro tary movement to each of the polishing-rolls, so that afresh polishing-surface comes in con tact with the wire at each reciprocation of the carriage.

It will of course be understood that the emery-boxes are covered, sothat it is impossible for the contents to iiy out, and, as alreadydescribed, I have so constructed the parts that it is impossible foremery to work into the bearings. Even if emery should fly out from theboxes it could not come in contact with any of the operative parts ofthe machine, but would drop upon the floor. When it is necessary to putin new polishingfrolls, it is simply required to remove the outer sides(denoted by of the emery-boxes and remove gears 12 from shafts 10, whenthe latter may be readily drawn out and the rolls removed.

The tension devices (denoted by 2) at the front of the machine requireno description, as any ordinary or preferred devices of this class maybe used.

The winding-drums are carried by a shaft, 43, at the opposite end of themachine. 44

denotes switch threads or worms mounted on this shaft, and 45 travelersmounted on arms 46, projecting from the framework. These travelersengage the switch-threads and cause longitudinally-reciprocatingmovement to the shaft,` so that the wire is wound evenly upon the drums.The rotary movement of the drums is imparted from lever 28 by means of apawl, 47, which engages a ratchet, 48, on shaft 43. In Fig. 2 this pawlis carried by a bell-crank lever, 49, pivoted to the framework, andconnected by an adjustable link, 50, to oscillating lever 28.

5l is a weight acting to hold the pawl in engagement with the ratchet.It will be seen that each movement of the oscillating lever toward theright will draw the upper arm of the bell-crank lever downward, andconsequently draw the pawl backward over the ratchet, while the returnmovement of the oscillating lever will raise the upper arm of thebell-crank lever, and with it the pawl, forcing the ratchet forward andimparting a rotary movement to the drums. In Fig. 7 the pawl is carriedby a lever, 52, the opposite end of which is provided with an incline,which is engaged by a roller, 53, on one of the oscillating levers. Aspring, 54, acts .to draw the forward end of the lever downward and holdthe pawl in engagement with the ratchet.

55, in both forms, is a pawl which engages the ratchet and acts to holdit against back ward movement. The operation is the same as in the otherform. It will of course be apparent that the slower the wire is woundupon the drums the more times the polishingmolls will pass over itssurface. The amount wound at each reciprocation of the carriage may bereadily adjusted by moving the point of attachment of link 50 to theoscillating lever up or down, in the form illustrated in Fig. 2, or bymoving roller 53 up or down, in the form illustrated in Fig. 7. Inpractice I usually wind about four inches of polished wire IOO IIO

IOl

380.162 Y g w at each reciprocation of the carriage. In order to reducethe wearupon the rolls to the minimum, I provide an adjustable guide,56, at the front of each emery-box, having an aperture, 57, of suitablesize and shape to permit the wire to pass through it freely, butl at thesame time to hold it against lateral movement. As the machine is shown'as acting upon a flat wire, the guide illustrated is shown as providedwith a corresponding aperture.

- 58 denotes set-screws passing through slots in the guide, whereby itis locked in any desired position.

Each time a new coil of wire is placed in the machine to be cleaned andpolished guide 56 is moved so that the wire comes in contact with anunused portion of the surface of the polishing-rolls.

The operation of the entire machine has been so thoroughly described indetail as to require but a brief recapitnlation.4 In starting themachine the strands of wire are passed through thetension devices, thenthrough the emeryboxes between the upper and under sets ofpolishing-rolls, and the ends are attached to the winding-drums.Theboxes are filled with emery, and the pressure of the polishing-rolls.upon the wire is then adjusted, and the machine is ready for theapplication of power.' In use the carriage lreciprocates backward andforward, causing the wirev to be thoroughly cleaned and polished by theaction of the emery and the rolls between which it passes. The rollshave no movement, except as actuated inthe manner described for thepurpose of continually changing the surface that is acting upon thewire. The movement of the carriage is sufficient, so that severalmovements of the polishing-rolls take place over each portion of thesurface of the wire. A

The machine is adaptedfor all sizes, shapes, and qualities of wire, andis found in practice to perfectly removea heavy oil-scale aftertempering, and to impart to the wire a perfect polish.

It will of course be understood that the details of construction aresubject to almost unlimited variation without departing from theprinciple of my invention.
